Method of use of electric hydraulic oil pump: When the electric hydraulic oil pump is used, the deflation nut should be opened, open the switch on the press, insert the power supply, and set the quick connector to the fast head applied to the hydraulic instrument.
The electric hydraulic oil pump can be used as a hydraulic pump of various hydraulic instruments. After the electric hydraulic oil pump is equipped with other hydraulic tools, it is possible to make a lifting, pressure type, eluting tube, bending, collections, shear, assembly, disassembly, etc. Reduce labor, improve work efficiency.
Application of Hydraulic Transmission: Hydraulic Transmission Technology is widely used in various aspects in industrial sectors, and hydraulic drive technology is widely used in various mechanical products to improve the level of automation, enhance product reliability and flexibility.
Disadvantages of hydraulic transmission: Hydraulic transmissions have the following disadvantages compared to other drives. (1) Strict gear ratio cannot be guaranteed due to leakage and liquid compressibility. (2) Hydraulic transmissions are more sensitive to changes in oil temperature, and should not work at very high and low temperatures. (3) Due to leakage, it is easy to pollute the surrounding environment.
The hydraulic pump (hydraulic jack) uses the characteristics of hydraulic transmission during use Compared with other transmissions, hydraulic transmission has the following advantages:
The torque of a hydraulic wrench does not start from 0, it is also determined by a special pump for a hydraulic wrench. Because the hydraulic wrench pump is a two-stage pump or a three-stage pump, whether it is a gear pump or a plunger pump at low pressure and large flow, the overflow is large, the pressure is unstable, and the output torque of the wrench is also unstable. Accurate torque measurement starts from the second stage, the second stage flow is much smaller than the low pressure flow, there is no overflow, stable, the torque can be accurately controlled.
